Display of generalized anaglyphs without retinal rivalry

Abstract

General anaglyphs may be rendered using multiple primary colors to display the first and second images of stereoscopic images. De-saturated primary colors are advantageous for rendering anaglyphs in six, five, four, and three primary colors. A white primary color is advantageous for displaying a monochrome second image with a color first image. General anaglyphs may be dynamically created by a display apparatus using certain transformations and communication with external sources. Colored viewing filters with de-saturated transmission spectra provide better color when viewing anaglyph images.
